I didn't see these. Further inspection shows that they're not in my copy of I have revision 1.13 from CVS, which one are you using?
I have a method in my JVM which makes a String object from an Ascii string. 

At the end I have this code:

  //Now return the value of String.intern
      jmethodID mid = CLASSFILE_FindMethod( env, ODEREF(hObjectTemp)->pstType, 
"intern", "()Ljava/lang/String;");
          return (*env)->CallObjectMethod( env, hObjectTemp, mid);
          eprintf("System method String.intern() not found, bailing out\n");
          assert(2 == 3);

Of course, this is potentially a serious speed killer, a JVM should make the 
string allocation as fast as possible.
